Table 1 Correlation of the four (three for O. sativa) developmental stages of species used in this study with floral developmental stages described elsewhere

From: A protocol for laser microdissection (LMD) followed by transcriptome analysis of plant reproductive tissue in phylogenetically distant angiosperms


Stage 1: carpel initiation

Stage 2: elongation of carpel walls

Stage 3: during meiosis

Stage 4: after meiosis


E. californica

0.39–0.65 mm BD: stage 5, carpel initiation

1.65–2.25 mm BD: stage 6, microsporangia initiate

2.3–2.8 mm BD: stage 8: male meiosis

3.5–5.5 mm BD: stage 9, female meiosis

Becker [12]

A. thaliana

0.3 mm BL: stage 5, sepals enclose bud

0.4 mm BL: stage 9, petal primordia stalked at base

0.5 mm BL: stage 11, stigmatic papillae appear

0.7–1 mm BL: stage 12, petals level with long stamens

Smyth et al. [13];

Armstrong and Jones [14]

O. sativa

0.9–1.5 mm IL: stage 6, differentiation of glumes

1.5–40 mm IL: stage 7, differentiation of floral organs

40–220 mm IL: stage 8. rapid elongation of rachis and branches
